As mentioned by Peter Hyde.... this is a function of large/small
fonts. Its actually the pixels per inch property of the screen
driver - not the card itself. Just out of interest, one of the
Borland guys said in the early days of D1 that if you toggle between
two ppi sizes, yopur components will slowly migrate to top-left. :-)
For development, we therefore insist that every machine has the same
video card and driver.
